    PLATE TOOLS, AGRICULTURAL EQUIPMENT O | / CONSIDERATIONS WHEEL PLATE TOOLS AND PROCEDURES FOR MANUFACTURE OF PLATE TOOLS Technical area This document refers to a plate tool for agricultural implements and a single tool.
    The disc tool is of a type that is particularly suitable for disintegrating crop residues after, for example, oilseeds, but also after maize or other crops, and which achieves working depths down to about 10 cm.
    Background It is known to cultivate soil using disc tools to achieve different types of soil improvement. In the case of certain types of crops, it is desirable to achieve relatively shallow tillage, about 1-3 cm, under the condition that plant residues located on the soil surface are chopped, ground or otherwise mechanically sprinkled.
    From then on, tillage is normally achieved over the width of the entire agricultural implement, ie. not just laterally separated from each other.
    Especially when growing rapeseed, it is desirable to grind down rapeseed plant residues, including stems and seed pods, in order to reduce the risk of diseases.
    A known such disc tool is shown in SE537123C2. This tool has radially extending, projecting parts radially extending towards the periphery, which resin cutting edges extend 15-75 degrees relative to the plane of the disc tool.
    Under certain circumstances, the plate tool shown in SE537123C2 may accumulate plant debris, such as straw and weeds, which means that processing needs to be interrupted for cleaning the tools. 5 2 There is a need for tools that can fulfill the same function, while having less need for cleaning and which can also be manufactured at low cost.

    Detailed Description Figs. 1a-1c show a disc tool 1 according to a first embodiment.
    The disc tool comprises a hub portion 10 and a machining portion 11. The hub portion is located at the central portion of the disc tool and is thus surrounded by the machining portion 11. The hub portion 10 is designed for connection to single storage, so that the disc tool 1 can be rotatably mounted relative to an agricultural tool 100, e.g. 4f. The hub portion 10 may comprise a flat portion, which surrounds a fastening device and whose radially outermost portion connects the processing portion 1 1. The processing portion 11 comprises a plurality of waves 111, 112, which have the decreasing amplitude of the counter hub portion 10. Specifically, the amplitude may decrease linearly toward the hub portion 10.
    At the radially outermost portion of the machining portion 11 there is a cutting edge E1, E2, which may be formed by oblique cutting or grinding of the piece of material from which the plate tool 1 is formed.
    The cutting edge E1, E2 is designed so that it for the most part, preferably to at least 90 ° /> of its length, consists of straight portions E1, E2.These straight portions E1, E2 can be separated by curved portions, as shown in Figs. 1c, or of recesses 213, 21, 313 shown in Figs. 2a-2c and in Figs. 3a-3c. l / led "straight sections" here refers to sections that are straight in at least one plane. Specifically, the straight portions shown in Figs. 1a-1c are straight in a plane containing the cutting edge, which is indicated by the lines at E1 and E2 in Fig. 1b.
    The straight portions have an angle of 30 ° -55 ° relative to a plane P which is perpendicular to the axis of rotation of the disc tool, but preferably 30 ° -50 °. Most preferably, the angle may be 35 ° -45 °. In the examples shown, the cutting edges of the disc tool can have, seen along the periphery, alternating angles, but with substantially the same amount +/- 5 °, towards the plane P.
    Each pair of adjacent straight portions E1, E2 has a mutual angle of 75 ° -115 °, preferably 85 ° -115 °, 95 ° -105 ° or 100 ° -105 °. As can be seen, the angle between each pair of adjacent straight portions E1, E2 is about 90 °.
    The cutting edges E1, E2 can have a maximum axial amplitude around 8-18 cm, and preferably 8-15 cm. Specifically, the amplitude can be 9-12 cm.
    Furthermore, the machining portion 11 to 40-60 ° /> can be located on the uniaxial side of said plane P and to 60-40 ° /> on the other axial side of plane P.
    The disc tool 1 in Figs. 1a-1c can be formed by compression molding a single, disc-shaped blank 1 ”of metal. The thickness of such a board blank may be in the order of 3-15 mm, preferably 5-10 mm. 7 The disc blank 1 ”, and the resulting disc tool 1 can have a diameter of about 400-700 mm.
    Specifically, the tool shown in Figs. 1a-1c is formed of a circular disc-shaped blank.
    The shaping can take place in that the disc blank 1 'is heated and then pressed by a pair of tools, comprising an upper part and a lower part, scales directed towards an axial plate are formed along a respective edge of the one tool part and scales directed towards a second axial plate are formed along a respective edge at the other tool part.
    Figs. 2a-2c show a second embodiment of a disc tool 2. This disc tool 2 has a recess 213, 214 extending radially inwards from the periphery, which is located at an imaginary point of intersection between two cutting edges E1, E2.
    The hub portion 20 may be identical to the hub portion 10 shown in Figs. 1a-1c. The machining portion 21, on the other hand, differs from that shown in Figs. 1a-1c.
    The design and extent of the scales 211, 212 may, in the case of the tool in Figs. 2a-2c, be the same as in the case of the tool in Figs. 1a-1c.
    However, the cutting edges E1, E2 of the tool in Figs. 2a-2c may be straight not only in one dimension, but in two mutually orthogonal dimensions.
    The recess 213, 214 may extend radially into a distance corresponding to 10-30 ° /> of a radius of the disc tool 2, preferably of one largest radius of the disc tool 2.
    The recess 213, 214 means that the stretching of the material which occurs at its outermost portion during the forming of the disc tool 2 from a planar disc blank 2 ”can be reduced, which can reduce the risk of crack formation and breakage of the finished disc tool 2.
    The recess 213, 214 may extend corresponding to a center angle rising to 1 ° -25 °, preferably 2 ° -15 ° or 2 ° -10 °.
    The plate tool 2 shown in Figs. 2a-2c can be formed on the basis of a quilateral polygonal disc blank 2 ”of metal. In the example shown, the sheet material is substantially pentagonally, two cutting edges being formed along each side of a pentagon. The disc blank 2 ”, and the resulting disc tool 28 can have a largest measured across (corresponding diameter) amounting to around 400-700 mm.
    Recesses 213 between cutting edges E1, E2 formed from different sides of the pentagon may be larger than recesses 214 formed intermediate cutting edges formed from one and the same side of the pentagon.
    Figures 3a-3c show a third embodiment of a disc tool 3. This disc tool 3 also has a recess 313 extending radially inwards from the periphery, which is located at an imaginary point of intersection between two cutting edges E1, E2.
    The hub portion 30 may be identical to the hub portions 10, 20 shown in Figs. 1a-1c and Figs. 2a-2c. However, the machining portion 31 differs from that shown in Figs. 1a-1c and in Figs. 2a-2c.
    The design and extent of the roads 311, 312 may, in the case of the tool 3 in Figs. 3a-3c, be the same as in the case of the tools 1, 2 in Figs. 1a-1c and in Figs. 2a-2c.
    In the tool 3 shown in Figs. 3a-3c, the recesses 313 can have a considerably greater radial extent, preferably about 40-60 ° /> of the largest radius of the disc tool 3.
    Furthermore, the recesses 313 may extend over a center angle which is smaller than that of the plate tool 2 in Figs. 2a-2c, preferably about 5 ° -10 °.
    The plate tool shown in Figures 3a-3c can be formed from a quilatable polygonal disc-shaped 3 ”blank of metal. In the example shown in Figs. 3a-3c, the disc blank 3 "is a triangular polygon, each cutting edge being formed from one of the edges of the polygon.
    The disc blank 3 ”, and the resulting disc tool 3 can have a largest dimension across (corresponding diameter) amounting to about 400-700 mm.
    The cutting edges E1, E2 of the tool 3 in Figs. 3a-3c can be straight not only in one dimension, but in two mutually orthogonal dimensions. Figs. 4a-4f show an agricultural implement 100 comprising a plurality of plate tools 1 according to Figs. 1a-1c. It will be appreciated that the disc tools 1 may instead be constituted by the disc tools 2, 3 according to Figs. 2a-2c or 3a-3c, or by a combination thereof. As can be seen from Figs. 4a-4f, each disc tool 1 is arranged on a self-arm 101, in a similar manner as in the initially mentioned SE537123C2.
    A plurality of such arms 101 may be arranged along a transverse end beam 102 of the agricultural implement 100. Preferably, the arms 101 are arranged at substantially the same distance from each other and evenly distributed over at least 90 ° / - ~ of the length 102 of the beam.
    Each disc tool 1 can be rotatable about an axis Ar, which can have an angle of 15 ° -20 °, typically normally 17 ° relative to the longitudinal direction of the beam 102. In the example shown, all the plate tools 1 on a beam are arranged on the same hob and with parallel axes of rotation Ar.
    As shown in Figures 4c-4f, the agricultural implement 100 may comprise at least two rows 110, 111 of tools, each row 110, 111 comprising a plurality of tools arranged on respective arms and distributed along a respective beam 102,1 12.
    Two such beams 102, 112 with disc tool 1 may be arranged so that the disc tools 1 on one beam 102 are offset in the transverse direction of the agricultural implement 100 relative to the disc tools 1 on the other beam 112. For example, the displacement may be about 80-120 ° /> axial extension tool ° / -. ~ +/- 5 ° />.
    Furthermore, the disc tools 1 on one beam 102 may have sine rotation axes non-parallel to the disc tools 1 on the other beam 12.
    For example, the disc tools 1 on one beam 102 may have sine rotation axes Ar inclined relative to the longitudinal direction of the beam by about 15 ° -20 ° in one direction and the disc tools on the other beam may have sine rotation axes inclined relative to the longitudinal direction of the beam by about 15 ° -20 ° in the other direction.
